Every seed begins life with a simple aim: to reach water, collect nutrients, and stay upright. Beneath the surface, root tips probe the soil and spread into branches that keep the plant alive.
Getting those branches to appear at just the right spot and moment matters even more now that weather swings between long dry spells and sudden cloudbursts.
Researchers have traced that timing to autophagy, the recycling pathway many people associate with health benefits from fasting.
By following a shape‑shifting protein through Arabidopsis roots, the team uncovered how brief clean‑up pulses let new branches form and help crops cope with tougher conditions.
